SPECIFICATION forming part of Letters Patentv No. 687,205, datedNovember 26, 1901. Appucation fusa January 21, 1901. senti No. 43,968.(No maa.)

To @ZZ whom t may concern:

Be it known that I, LEWIS P. DELANO, a citizen of the United States,residing at the city of St. Louis, in the State of Missouri, haveinvented a certain newand useful Journal- Bearing, of which thefollowing is such a full, clear,and exact description as will enable anyone skilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, forming part of thisspecification. Y

My invention relates lnore particularly to that class ofjournal-bearings described in my previous application, Serial No.30,888, .filed September 24, 1900,which class of bearings consists inthe combination of an outer shell, an inner shell forming part of thewearing-surface, and afllling of fusible metal also forming part of thewearing -surface and holding said shells together.

The object of my invention is to provide additional means for preventingthe rotation of the inner shell and fusible filling in the outer shell,a tendency to such rotation being continually exerted by the friction ofthe axle on the wearing-surface of the bearing when the axle is inmotion.

My invention, broadly stated, consists in the combination of an outershell or casing provided with one or more keyways, of an inner shellalso forming part of the wearingsurface and provided with one or morekeys iitting in said keyways, and a filling of fusible metal alsoforming part of the wearingsurface and holding said shells together.

In the accompanying drawings,which illus.

trate one form of bearing made in accordance with my invention, Figure 1is a plan view of the outer shell or casing. Fig. 2 is avplan view ofthe complete bearing. Fig. 3 is a section on the line 3 3 of Fig. 2.Fig. 4 is a plan view showing the inner shell removed from the outershell, and Fig. 5 is a slightly-enlarged section on the line 5 5 of Fig.2.

Like marks of reference refer to similar parts in the several views ofthe drawings.

10 is the inner shell or casing of the bearing. The shell or casing 10is composed of a central stripll and lateral strips 12.. The lateralstrips 12-are preferably spirally disposed, as shown in Figs. 2 and 4.The shell 10 is providedat the ends with flanges 13 and 14. Projectingdownwardly from the central strip 11 is a rib 15, which rests upon thebottom of the outer casing or shell, to be hereinafter described. Theunder face of theV shell 10 ismade concave, so as to fit the axle ofacar. The shell 10, so far as described, is like that shown anddescribed in my previ= ous application above referred to. In addition,however, it is provided with two keys 16 and 17, which keys are formedintegral forms to the general shape of the top of the shell 10. Thecasing 18 is preferably provided at its centerwith a flat groove 19,which is adapted to receive the downwardly-projecting rib of the innershell 10. On each side ofthe groove 19 arepreferably provided lone ormore lugs 2O to hold the shell 10 from rotation in the shell18 by meansof their con-V tact with the rib 15. Formed on the inner face of theshell 18, near each edge, is arib 21.

' The outer shell 18, so far as above described,

is the same as that described in my previous application. In addition,however, it is provided at each end with a keyway 22, which is adaptedto receive one of the keys 16 or 17 on the flanges of the inner shell10.

23 is the filling, of Babbitt or other fusible metal, which is castbetween the inner and outer shells to hold the same together and whichalso forms a portion of the wearingsurface by extending between thestrips 12, flush with the faces of said strips.

In forming my bearing the outer. shell 18 and the inner shell 10 arecast separately. The inner shell 10 is made of bronze, brass, or othersimilar hard metal. -The outer shell 18 is preferably made o fcast-iron, but may be made of any other suitable hard metal. Theinnershell 10 is placed in position within the outer shell 18, the rib15 extending into the groove 19 and the keys 16 and 17 extending intothe keyways 22. The two shells are then placed around a suitable mandrelor axle, and the Babbitt or other fusible metal 23 is then cast betweenthe two shells, holding the same together. The use of the keys 16 andIOO 17, extending into the keyways 22, positively and effectivelyprevents any tendency of the inner shell and the iilling to turn in theouter shell. It will therefore be seen that I may dispense with the useof the lugs 20, which coperate with the rib 15 to prevent the rotationof the inner shell. I prefer, however, to use these lugs in addition tothe keys 16 and 17.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent of the United States, is

1. A journal-bearing consisting of an outer shell or casing having akeyway formed in one end thereof, an inner shell forming part of theWearing-surface and provided at one end with a iiange, a key formedintegral with said iiange and fitting in said keyway, and a iilling offusible metal holding said shells together and also forming part of theWearingsurface.

2. A journal-bearing consisting of an outer shell or casing provided ateach end With a keyway, an inner shell forming part of thewearing-surface and provided at each end with a flange, a key formedintegral with each of said flanges and fitting into the keyways in saidouter shell, and a filling of fusible metal holding said shells togetherand also forming part of the wearing-surface.

3. A journal-bearing composed of an outer shell or casing having akeyway formed in one end thereof and provided with a central groove, andan inner shell consisting of a eentral strip adapted to fit in saidgroove and lateral strips projecting therefrom, there being a iiange atone end of said inner shell and a key of substantially the same width assaid central strip and formed integral therewith and with said flange,said key projecting into said keyway, and a filling of fusible metalholding said shells together and also forming part of thewearing-surface.

In testimony whereof I have hereunto set my hand and affixed my seal inthe presence of the two subscribing witnesses.
